An electrostatic paint sprayer is used to coat a metal bicycle frame with paint.

The diagram shows the sprayer nozzle emitting paint droplets towards a section of the metal frame.

A diagram showing an electrostatic spray gun on the left emitting a cloud of fine paint droplets. To the right is a cylindrical section of a metal bicycle frame. An earth wire with a grounding symbol is connected to the metal frame.

The metal bicycle frame is connected to the ground (earthed).

Explain how charging the paint droplets helps to ensure that the bicycle frame gets an even and complete coating of paint.
